Fatal error when Order Quantities is activated

Hi

We’ve logged this as a confirmed bug and will include the official fix in the upcoming Booster update.

In the meantime, if you’d like to apply the patch manually to prevent the crash right away, please follow the steps below:

File path (depending on your installed booster version):

If you are using booster elite version

/wp-content/plugins/booster-elite-for-woocommerce/includes/class-wcj-order-quantities.php

If you are using booster plus version

/wp-content/plugins/booster-plus-for-woocommerce/includes/class-wcj-order-quantities.php

If you are using booster free version

/wp-content/plugins/woocommerce-jetpack/includes/class-wcj-order-quantities.php

Locate this function: "set_quantity_input_max"

Note : Before making any changes, please back up the original file to avoid any potential issues.

Replace it with the following code:

public function set_quantity_input_max( $qty, $_product ) {

    // Prevent recursion to avoid memory exhaustion

    static $depth = 0;

    if ( $depth > 0 ) {

        return $qty;

    }

    $depth++;

    // Handle variable products normally

    if ( $_product->is_type( 'variable' ) ) {

        $depth--;

        return $qty;

    }

    // Apply Booster max logic

    $plugin_max = $this->get_product_quantity( 'max', $_product, $qty );

    $wc_max     = $_product->get_max_purchase_quantity();

    $depth--;

    // Return the correct limit

    return ( -1 === $wc_max || $plugin_max < $wc_max ) ? $plugin_max : $wc_max;

}

This fix will be officially included in our upcoming update so that no manual patch will be required going forward.
